Abstract

Методът намира приложение в химическата промишленост. С него се подобряват селективността в окислителната реакция на пропилена до акролеин и окисляването на акролеина до акрилова киселина. Методът се състои в двуетапно каталитично окисление на пропилен, при който в първия етап се получава предимно акролеин, а във втория акрилова киселина чрез окисляване на акролеина, като се използват един или повече рециркулационни захранващи потоци, съдържащи кислород и инертен разреждащ газ или във всеки етап, или в двата. Разреждащият газ в първия етап съдържа от 0 до 0,4 мол вода пара/мол пропилен, а остатъкът от него представлява един или повече инертни газове. Разреждащият газ трябва да има съставен топлинен капацитет най-малко 6,5 кал/г-мол /с0/ при молно съотношение към пропилена от 2 до 32. Във втория етап газът съдържа един или повече инертни газове със съставен топлинен капацитет най-малко 6,5 кал/г-мол /с0/. 5 претенцииThe method finds application in the chemical industry. It improves the selectivity in the oxidation reaction of propylene to acrolein and the oxidation of acrolein to acrylic acid. The method consists of a two-stage catalytic oxidation of propylene, in which in the first stage acrolein is produced primarily and in the second stage acrylic acid is obtained by oxidizing acrolein using one or more recirculating feed streams containing oxygen and an inert diluent gas or in each stage , or in both. The diluent gas in the first stage contains from 0 to 0.4 moles of water vapor/mol of propylene, and the remainder is one or more inert gases. The diluent gas must have a composite heat capacity of at least 6.5 cal/g-mol /c0/ at a molar ratio to propylene of 2 to 32. In the second stage, the gas contains one or more inert gases with a composite heat capacity of at least 6 .5 cal/g-mol /c0/. 5 claims
